Topic 2a - Carbon Dioxide

Introduction

This activity covers some of the material found in Topic 2 of the Environmental
Chemistry module. The information is presented on a series of pages. Most
of the pages finish with a quiz in which you must answer questions by clicking
on various parts of an image or typing words into a box. The questions
are asked in a random order and you must answer them all correctly before
you will be allowed to proceed. Each time you make a mistake the quiz will
automatically restart. When you complete a quiz you will be given a clearance
code which you should note down for later use on the clearance page. At
the end of the set of quizzes you should print out a copy of the clearance
certificate and hand this in to your teacher as proof that you have completed
the activity.
